Anchor QEA  was the lead consultant retained by a group of primary responsible parties (PRPs) to perform CERCLA design and construction support services for this federal contaminated sediment site in Tacoma, Washington.  As the construction manager for the project, Anchor QEA chose a “partnered” approach to the project with the contractor, Manson Construction Company.  The Anchor QEA team completed the project within the established timeframe and within the client’s budget parameters with no claims.   

The project consisted of dredging/disposing over 100,000 cubic yards of contaminated sediment, placing 40,000 tons of cap/backfill material, installing a new bulkhead, demolishing 70,000 square feet of overwater structures, and enhancing shoreline fish habitat.  The work was complicated by the need to comply with restricted fisheries work windows and to keep the owners’ active ship repair and tug boat operations open during construction.  The results of the project have been considered successful by the PRPs and regulatory agencies.  Anchor QEA won an award of merit from the Construction Management Association of America, Pacific Northwest Chapter for our construction management work on the project.

In addition to construction management services, Anchor QEA was the project coordinator for the Middle Waterway Cleanup and had involvement throughout the cleanup process, beginning with strategy development (in response to the Record of Decision) and negotiation of an Agreed Order on Consent and Statement of Work.  Anchor QEA also completed a biological assessment, remedial design (including bid documents), and obtained necessary permits for construction. Anchor QEA is continuing project services by providing long-term monitoring of the constructed project amenities.
